The Boardman Police Department has released surveillance video taken last month during an “active-shooter” exercise at Boardman High School where one of the participants ended up getting hurt.

The drill was held in March and was staged to see how local police and others would respond in the event of an actual shooting at the school. At one point, teacher Jesse McClain, acting as a parent in the scenario, ran into a building and was tackled to the floor by a police officer. McClain suffered a broken shoulder.

Boardman Police Chief Jack Nichols said the department’s Internal Affairs Division is reviewing to incident to determine if action should be taken.
